SPECIFICATION blmng' :part 0f 'Letters' :Patent NO. 725,052, dated.April 14, 1903.

Application filed September 27, 1902. Serial No. 125,133. (No model.)

To @ZZ whom it may oon/cern:

Be it known that I, NVILLIAM CHARLESVDIL- LON, a citizen of the UnitedStates residing at Los Angeles, in the county of Los Angeles and Stateof California, have invented a new and useful Weather-Strip, of whichthe following is a specication.

My invention is an improved weather-strip for doors; and the object ofmy device is to produce a 'weather strip which will bear closely againstthe door, thus forming an airtight joint and at the same time permit thedoor to be easily opened and closed, and also to provide a weather-stripin which the wear will be automatically taken up, and I achieve theseobjects by means of a strip which is raised into contact with the loweredge of the door when the same is closed and dropped below the level ofthe sill when the door is opened, and I thus gain anotheradvantage,inasmuch as the strip does not project above the sill when the door isopen.

In the accompanying drawings, Figure lis a perspective view showing thepractical application of my improvement, a portion of the door step andsill being broken away. Fig. 2 is a detail View, parts being brokenawayand the means for raising the strip being shown in elevation. Fig. 3is a sectional view about on the line 3 3 of Fig. 2. Figs. 4 and raredetail views of the two sections of my weatherstrip detached.

In the construction and installation of my improvement a longitudinalslot A is produced in the sill A', and this slot is continued downward,forming a groovein the jamb or door-step A2 beneath the sill. Afrectangular block B is longitudinally grooved along its upper face, andinto this groove is secured the weather-strip C. Onthe under face ofthis block are formed recesses I3', having in wardly-inclined sides.Beneath the block B is a block D of similarlength, having a smooth undersurface and beveled shoulders D on its upper surface, the block D beingadapted to slide in the slot A, and the beveled shoulders are adapted torest in the recesses B when the door is open, as will be seenhereinafter. The side jamb of the door is recessed at E, this recesshaving communication at the bottom with the longitudinal slot A. In therear of the recess is a spring F, secured to the jamb at its lower'endand curved outwardly intermediate its ends. A bent lever G is pivotedintermediate its ends to one side of the recess, and its upper end isbent outward. Its lower end is pivotally secured to one end of the blockD. A metallic wear-plate H is secured to the edge of the door.

The operation of my weather-strip is as follows: When the door is open,the spring F will force the bent end of the lever outward, and the lowerend of the lever will be drawn into the rear of the recess, drawinginward the block D, the shoulders D fitting into the recesses B, and theweather-strip will lie bea low or flush with the sill. When the door isclosed, the wear-plate contacts with the bent end of the lever andforces it inward, throwing the lower end outward. This movement forcesthe shoulders D out of the recesses and under the non-recessed portionof the block B, thus raising the weather-strip above the surface of thesill and forcing itY against the lower edge of the door.

Having thus fullydescribed my invention, what I claim Vas new, anddesire to secure by Letters Patent, is-

The combination with a grooved door-sill, a door-jamb recessed in itslower portion, a block having beveled shoulders adapted to slide in saidgroove, a second block vertically movable in said groove having aweatherstrip on its upper surface and recessed to receive the beveledshoulders on its under surface, a lever pivoted intermediate its ends inthe recess of the door-jamb and at its lower end to the slidable block,and a springadapted 'to force the free end of the lever forward.
